Can you mill EPP? I was wondering if I could mill the main wing.
It flies fine at its target weight. The wing is only 5mm thick, so with EPP being quite floppy I don't think that milling it would be as beneficial as milling depron. Coonak got his one to 190g AUW without milling the wing. Perhaps look at saving weight on the components and that may get you to your target weight.
